Review: OEM product, perfect - Product as recommended by Subaru: APPROVED 100%, thanks! Review: Boy does this stuff stink! - Still trying to get the smell out of the garage and off my hands. Did front and rear differential at 30-35k miles (since last changed) on a 5th gen Outback XT Limited a couple days ago. Daily driver, mostly commuting. The front takes about 1.4 qts plus a bit of waste and the back takes about 0.8 qts. This 5-quart bundle should thus cover two complete fluid changes. Looking at the old fluid, honestly it looked new, especially the rear, so I think it could probably handle a longer change interval. Be prepared for weirdness in fastener choices. I looked at about 5 different tutorials and saw 5 different combinations of fasteners. Ours has T70 Torx front drain plug (most sets don't go this large), 14mm bolt front overflow, breather/fill plug just pushes into place (passenger side under the intercooler). Rear is a 10mm Allen socket for the drain plug, 17mm bolt for the fill plug. ## Features - 5 quarts of genuine Subaru 75w-90 High Performance Gear Oil - SOA427V1700 x5 - For use in MANUAL transmissions only. - 5 & 6 Speed manual transmissions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0731SB4M3 | | Best Sellers Rank | #43,403 in Automotive ( See Top 100 in Automotive ) #117 in Transmission Fluids | | Brand | Subaru | | Brand Name | Subaru | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 310 Reviews | | Item Form | Liquid | | Liquid Volume | 5 quarts | | Material | Synthetic | | Number of Packs | 5 | | Package Information | Bottle | | Part Number | SOA427V1700KIT | | Recommended Uses For Product | Transmission Fluid | | SAE J300 Viscosity Grade | 75W-90 | | Specific Uses For Product | Manual Transmission Lubrication | | UPC | 752589526142 | | Unit Count | 160 Fluid Ounces | | Viscosity | 75W90 | ## Product Details - **Brand:** Subaru - **Liquid Volume:** 5 Quarts - **Material:** Synthetic - **Package Information:** Bottle - **Recommended Uses For Product:** Transmission Fluid ## Images ![Subaru 75W90 Extra S Gear & Transmission Fluid - 5 Quart Bottles Sti WRX Genuine SOA427V1700 X5 - Image 1](https://m.media-amazon.com/images/I/71T2FM4k6+L.jpg) ![Subaru 75W90 Extra S Gear & Transmission Fluid - 5 Quart Bottles Sti WRX Genuine SOA427V1700 X5 - Image 2](https://m.media-amazon.com/images/I/71vTxBYkAgL.jpg) ## Questions & Answers **Q: 1) is this meant for the manual 2018 wrx (not an sti) and it’s rear diff? 2) how is this made in the usa? i thought it was from japan?** A: this will work in the manual transmission and the diff. Subaru make things in the US to avoid tariffs. **Q: Is the oil with limited slips?** A: This oil can be used for the transmission and the front and rear differential. The best thing to do is call a Subaru dealership and talk to the maintenance department. Some times it is even cheaper there than on Amazon. When i got the coolant it was twice the price here than at the dealership. **Q: Is this full synthetic?** A: This product is not synthetic, it is a Subaru manual transmission specialty mix recommend by Subaru for manual transmission's and rear differentials. I recently purchased 5 quarts for my 2010 Outback 6 speed and am very pleased with the product. **Q: How many quarts do i need for a subaru wrx sti (2015+)? i am seeing it's around 6 quarts. is that correct? make a 6qt pack.** A: 4.25-4.5 quarts transmission 1.25-1.75 quarts rear differential, you’ll need a pump adapter to place onto the bottle ## Customer Reviews ### ⭐⭐⭐⭐⭐ OEM product, perfect *by H***O on February 1, 2026* Product as recommended by Subaru: APPROVED 100%, thanks! ### ⭐⭐⭐⭐⭐ Boy does this stuff stink! *by T***S on July 27, 2026* Still trying to get the smell out of the garage and off my hands.

After replacing many other parts, I decided to go the OEM route out of curiosity and wow. Smooth to shift into gear, easy to take off, no more rocking back and forth, no more noises and friction. I am appalled that I didnt trust the OEM fluids first.. Subaru has two engines. Of course they are going to perfect that formulation and they did it well. No complaints other than I was stupid and didn’t buy this first. ## Frequently Bought Together - Subaru 75W90 Extra S Gear & Transmission Fluid - 5 Quart Bottles Sti WRX Genuine SOA427V1700 X5 - Subaru Transmission or Torque Converter Case Plug 26.3 x 32.3 x 1 Gasket - 803926090 - Genuine OEM - Powerbuilt T-70 Star Bit Socket, 1/2 Inch Drive, Torx, High Visibility Size Marking - 940363 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/44140990-subaru-75w90-extra-s-gear-and-transmission-fluid-5-quart](https://www.desertcart.tn/products/44140990-subaru-75w90-extra-s-gear-and-transmission-fluid-5-quart) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-05*
